1 Even before Pearl Harbor,
the War Plans Division (WPD) occasionally produced
maps, such as this, presenting a tabulation
of Army strength in the overseas bases. On
3 January 1942, WPD began regularly to issue
a Weekly Status Map, showing the current and
projected development of personnel and aircraft
overseas, area by area. These maps were continued
by WPD's successor, OPD, until the fall of
1944 (for example, Charts 2 and 3). The data
contained in these maps did not necessarily
correspond with other statistical records kept
in Washington or in the field. But this simplified
accounting was the most reliable rough summary
on Army deployment readily available to General
Marshall and the whole War Department for planning
purposes. See Cline, Washington Command
Post: The Operations Division, pp. 87,
1293b.
